the i trackway. l

An important object of theinvention the provision of a trackway which maybe adjusted vertically,` eliminating the' necessity of moving the main or bodyportion of the supports, in order to make the necessary adjustments for the maintenance of the track rails inzproper parallel 'relation with each other, due consideration being given to the strength and durability of the trackway.

A further object of the invention is the provision of means whereby the height and inclination of the trackway may be changed to facilitate the use of thet'rackway with Y varying tide and water conditions.

lVith the foregoing and other objects in view which will appear asthe description trackway is indicated generally by the reference character 5.and is shown as having its lower end disposed in a planehsubstantially The upper end of thegtrackway `5 is supported by the platform6,which in turn is supportd by the frame work 7 including Yhorizontal bars 8 on whichv thesupporting beams 9 of the platform are s-ecured.

v l Securing membersjlOjare mountedo-n the bination and arrangement of part-s and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. f

Referring to the drawings:

Figure V1 is a side elevational view of a trackway constructed in accordance with the invention. n

Figure 2 is a sectional view taken on line 2 2 of Figure 1.

12that` cooperate with the depending ears 13 formed at the ends of thebar 114. which is secured to theupper ends ,of theiangle bars and flat. bars forming the supporting` members 'of the trackway, so that the upper endof thetrackway will be pivotallysupported `for vertical adjustment but heldV rigid against movement y longitudinally of the proceeds, the invention resides,` in the. complatform. l,

y The trackwayfomprises anglebars 1 5 that are arranged to provide the lateral supporting members for the track proper between which angle bars are positioned the rela- .tively flat bars 16, which bars are as shown,

secured to the angle bars 15, as shown by.

Figure 3 of the drawings Angle irons 19 are 1 bars 15 and act as supports for the angle olted to the anglel `lowerlsections 222 "and f upper threaded sections 23. Fitted in the upper end of( each lowerfsection 22 is a 'bearing Ymember 24 in which the adjusting sleeve" 2operates, the adjusting sleeve beingformed with internal i vspaced teeth 25idesigned' tocooperate with the threads -26 of the upper section yassociated therewith.

The upperf extremity l of each lsection 26 is flattened as atf26"and is "providedfwit'h an *opening27 for the reception of' theI bolts 28 that also extend through the ears 29r4 fde- `pending from the trackway; to pivotally con- 4nectthe` sections 26-'to the trackway; In order that theadjustinfg sleeves 25 will Vbe -held'against upward movement, lugs y27are provided adjacent to the lower' ends thereof, which lugs'move in the 'key-'ways' 28 ofthe bearingm'embers 24 and Awhenproperly posif tioned,C lie lunder thei lower' ends of 'thebeari ing Ymembers'V 24l 'as shm'vn'byT Figure 44.?

` T-he upper section-"of each supportl is also t formed: witlr a 'longitudinal :groove (28, to the end'thatshculd vlit bedesiredtc remove the upper sections; the upper-sections Imaybe ro- Vtated -unt`ilf the grooves Ifall opposite the spaced teeth 25 V'whereuponthe" upper ysections be' lifted.

Y Fromme foregoing awa-1 be obvious that by rotating 'the adjusting members 25, lthe trackway may be kadjusted --vertically i-roughoutl itsfl'enfg'th; ktInforder''that the trackway will be braced against creeping, horizontal bracing bars 29 are provided, which are shown as connecting adjacent supporting members of the trackway.

Steps indicated at 30 may be provided so that persons may pass from the water after ytheyrhavev glided over the traclrway on a toboggan or coaster, to again seat themselves for another ride over the trackway.

Flanges 81 are formed on the adjusting members 25 {andi-.afford means whereby a wrench or other suitable tool may be positioned thereon to rotate the adjusting members 25 to accomplish. the adjusting feature.

'From the foregoing detail description, yit is believed thatfa further Edetail description sary.
